4.1.2.2 Connection method

Within the device most gas connections have been implemented via a FAST connector
(FAST – Fast, Save, Tight). These connectors provide a tight transition between the hoses
and connections with different diameters. The soft sleeves prevent the risk of glass fractures
compared to rigid screw connections. There are different versions of the connectors.

In addition, so-called Fingertight screw connections are used in the analyzer mul-
ti N/C pharma HT. These flangeless fittings consist of a conical nipple and a banjo bolt.
These hose connections seal purely by tightening the plastic banjo bolt finger-tight.

4.1.2.3 Components for flow adjustment

The flow of the carrier gas is adjusted automatically in the multi N/C pharma HTS and the
inlet flow is controlled via an MFC (mass flow controller). At the device outlet the carrier gas
flow is measured using an MFM (mass flow meter), i.e. an automatic tightness check is car-
ried out. The result is displayed in the control and analysis software multiWin in the window
System state.
The NPOC purging flow is adjusted via a needle valve left to the combustion furnace at the
gas box. It is only accessible with the left side wall removed. The NPOC purging flow is
measured using an MFM and displayed in the control and analysis software in the window
System state.
